Not much else is known about the ZenFone 4, but we will know more in the upcoming weeks. ASUS is expected to launch ZenFone 4, ZenFone 4 Pro, ZenFone 4V, and ZenFone 4 Selfie and while we don't know if all four phones will be launched at the same time, the ZenFone 4 should be the first one to make its debut.
